Mo Hua had tried it before, the collapse of the Compound Formation, and the ensuing inversion of spiritual power, could indeed harm the Feng Xi.
However, the Blood Qi of Feng Xi was too strong, and its regeneration was swift; the collapse of formations in small areas wasn't enough to kill it, but the collapse of large-scale formations was completely different.
If the entire Large Formation were to collapse, just how powerful would the resulting collapse energy be...
Mo Hua tried to imagine it and couldn't help but feel a tremor in his heart.
It would be best not to come to that...
Building a Large Formation would be an arduous task that required an immense amount of manpower and resources; Mo Hua was reluctant to let it go to waste.
However, if there was spare time, it would still be necessary to calculate the Large Formation with Divine Sense Calculation, to be prepared in advance.
